  SAP Error Message:
  WY136 FM &1; parameter transfer incorrect (missing parameters)
  
  
  Cause:
  This error occurs when a function module (FM) is called with an incorrect or incomplete set of parameters. Specifically, the function module expects certain parameters to be passed during the call, but some required parameters are missing or not properly transferred.
  In SAP, function modules have defined importing, exporting, changing, and tables parameters. If the calling program or another FM does not supply all mandatory parameters, or if the parameter structure is incorrect, the system raises this error.
  
  Typical Scenarios:
  
  Calling a standard or custom FM without all required parameters.
  Incorrect parameter names or types used in the call.
  Parameter structure mismatch due to changes in FM interface.
  Missing parameters in dynamic FM calls (e.g., CALL FUNCTION with dynamic names).
  Issues in wrapper or proxy programs that call the FM.
  
  
  
  Solution:
  
  
  Check the FM Interface:
  
  Go to transaction SE37.
  Enter the function module
